| 摘 要： | 在深入分析路径规划数据结构的基础上,给出了一种用于车辆导航的路径规划数据逻辑模型。首先给出了路径规划数据的组成要素,阐述了各组成要素之间的相互关系,然后给出描述各类要素状态与特征的属性组成。通过实践证明,路径规划数据逻辑模型的建立对于制定导航数据物理存储格式、指导导航数据的格式转换与数据生产具有重要的意义。

| Abstract: | On the basis of analysis of route planning data structure,this paper proposed a logic model of route planning data for vehicle navigation.First,this paper described features included in route planning data and then elaborates relationships between these features.Finally, it described the attributes of these features.It has been proved that the establishment of the logic model of route planning data is significant for designing of physical storage format for navigation data.Besides,it can direct the conversion and production of navigation data. |
